00:00:00 --> 00:00:02 welcome to astronomy daily your source
00:00:02 --> 00:00:04 for the latest space in astronomy news
00:00:04 --> 00:00:06 I'm your host Anna and today we've got
00:00:06 --> 00:00:08 an exciting lineup in store for you
00:00:08 --> 00:00:10 we'll be diving into some fascinating
00:00:10 --> 00:00:12 stories from Voyager 1's latest
00:00:12 --> 00:00:14 communication challenges at the edge of
00:00:14 --> 00:00:16 our solar system to intriguing new
00:00:16 --> 00:00:19 discoveries about potential ocean worlds
00:00:19 --> 00:00:20 from the furthest reaches of human
00:00:20 --> 00:00:22 exploration to surprising findings
00:00:22 --> 00:00:24 closer to home we've got a packed show
00:00:25 --> 00:00:26 ahead that you won't want to
00:00:27 --> 00:00:29 miss let's dive into our first story of
00:00:29 --> 00:00:31 the day which takes us to the very edge
00:00:31 --> 00:00:33 of human exploration NASA's legendary
00:00:33 --> 00:00:36 Voyager 1 spacecraft now an astounding
00:00:36 --> 00:00:38 15 billion miles from Earth recently
00:00:38 --> 00:00:40 gave its team quite a scare when it
00:00:40 --> 00:00:43 temporarily fell silent after Decades of
00:00:43 --> 00:00:45 faithful service the spacecraft's
00:00:45 --> 00:00:47 communications went dark triggering an
00:00:47 --> 00:00:50 intensive effort to reestablish contact
00:00:50 --> 00:00:53 the drama began on October 16th when the
00:00:53 --> 00:00:54 flight team sent what should have been a
00:00:54 --> 00:00:56 routine command to turn on one of the
00:00:56 --> 00:00:59 spacecraft's heaters despite having
00:00:59 --> 00:01:01 sufficient power for this operation
00:01:01 --> 00:01:04 something unexpected happened the
00:01:04 --> 00:01:06 spacecraft's fault protection system was
00:01:06 --> 00:01:08 triggered leading to a series of
00:01:08 --> 00:01:10 communication challenges the situation
00:01:10 --> 00:01:13 became even more complex when Voyager
00:01:13 --> 00:01:15 switched from its usual x-band radio
00:01:15 --> 00:01:18 transmitter to a backup s-band system
00:01:18 --> 00:01:21 something it hadn't used since 1981 this
00:01:21 --> 00:01:23 was particularly concerning because at
00:01:23 --> 00:01:25 such an enormous distance the weaker
00:01:25 --> 00:01:26 sban signal might not have been
00:01:26 --> 00:01:29 detectable from Earth at all imagine
00:01:29 --> 00:01:30 trying to trouble shoot a computer
00:01:30 --> 00:01:32 problem but instead of being able to
00:01:32 --> 00:01:34 walk over and check what's wrong your
00:01:34 --> 00:01:37 commands take 23 hours just to reach the
00:01:37 --> 00:01:39 device and another 23 hours to get a
00:01:39 --> 00:01:42 response back that's exactly what NASA's
00:01:42 --> 00:01:43 Engineers faced as they worked to solve
00:01:44 --> 00:01:46 this puzzle across the vast expanse of
00:01:47 --> 00:01:49 space thankfully through some impressive
00:01:49 --> 00:01:52 detective work and Engineering expertise
00:01:52 --> 00:01:54 NASA successfully reestablished contact
00:01:54 --> 00:01:57 with Voyager 1 on October 24th the
00:01:57 --> 00:02:00 spacecraft appears to be stable though
00:02:00 --> 00:02:01 Engineers are still working to
00:02:01 --> 00:02:03 understand exactly what triggered these
00:02:03 --> 00:02:06 issues in the first place this incident
00:02:06 --> 00:02:07 serves as a reminder of both the
00:02:07 --> 00:02:09 remarkable longevity of the Voyager
00:02:09 --> 00:02:12 Mission now over 47 years old and the
00:02:12 --> 00:02:14 increasing challenges of maintaining
00:02:14 --> 00:02:17 such aging spacecraft in the Uncharted
00:02:17 --> 00:02:19 Territory of interstellar space it's
00:02:19 --> 00:02:21 truly remarkable that we can still
00:02:22 --> 00:02:24 communicate with this Pioneer of space
00:02:24 --> 00:02:26 exploration even as it Ventures further
00:02:26 --> 00:02:29 into the unknown than any human-made
00:02:29 --> 00:02:31 object in history
00:02:31 --> 00:02:33 in a significant step for China's space
00:02:33 --> 00:02:37 program a new crew of three astronauts
00:02:37 --> 00:02:39 successfully launched to the tangang
00:02:39 --> 00:02:41 space station in the early hours of
00:02:41 --> 00:02:44 Wednesday morning the sheno 19 Mission
00:02:44 --> 00:02:47 lifted off at 427 a.m. local time from
00:02:47 --> 00:02:49 the jukon satellite launch Center in
00:02:49 --> 00:02:51 Northwest China marking another
00:02:51 --> 00:02:53 milestone in the nation's ambitious
00:02:53 --> 00:02:55 space exploration Journey among the crew
00:02:56 --> 00:02:58 is 34-year-old Wang howy who joins the
00:02:58 --> 00:03:01 elite ranks as China as third woman to
00:03:01 --> 00:03:04 participate in a crude space mission
00:03:04 --> 00:03:06 what makes Wang particularly noteworthy
00:03:06 --> 00:03:09 is her role as the country's only female
00:03:09 --> 00:03:11 space flight engineer bringing unique
00:03:11 --> 00:03:14 technical expertise to the mission the
00:03:14 --> 00:03:17 crew is led by veteran astronaut Kai sua
00:03:17 --> 00:03:19 a 48-year-old former Air Force pilot who
00:03:19 --> 00:03:21 brings valuable experience from his
00:03:21 --> 00:03:22 previous stint aboard tiangong during
00:03:23 --> 00:03:25 the sheno 14 mission in
00:03:25 --> 00:03:27 2022 rounding out the team is
00:03:27 --> 00:03:30 34-year-old s lingdong completing this
00:03:30 --> 00:03:32 carefully selected Trio of Space
00:03:32 --> 00:03:34 Explorers during their approximately
00:03:34 --> 00:03:37 6-month stay aboard Chang gong the crew
00:03:37 --> 00:03:38 will conduct various scientific
00:03:38 --> 00:03:40 experiments with a particularly
00:03:40 --> 00:03:42 interesting focus on testing special
00:03:42 --> 00:03:44 bricks made from materials that simulate
00:03:44 --> 00:03:47 lunar soil This research directly ties
00:03:47 --> 00:03:49 into China's broader Ambitions of
00:03:49 --> 00:03:50 establishing a human presence on the
00:03:50 --> 00:03:53 Moon by 2030 these lunar soil
00:03:53 --> 00:03:56 experiments are especially significant
00:03:56 --> 00:03:57 as scientists hope to eventually use
00:03:57 --> 00:04:00 actual moon materials for constru their
00:04:00 --> 00:04:02 plan lunar base potentially
00:04:02 --> 00:04:04 revolutionizing how we approach
00:04:04 --> 00:04:05 off-world
00:04:05 --> 00:04:07 construction this Mission represents
00:04:07 --> 00:04:09 more than just another crew rotation
00:04:09 --> 00:04:12 it's a crucial stepping stone in China's
00:04:12 --> 00:04:14 expanding Space Program the country has
00:04:14 --> 00:04:16 made remarkable progress in recent years
00:04:17 --> 00:04:18 including successfully Landing Rovers on
00:04:19 --> 00:04:21 both Mars and the moon and establishing
00:04:21 --> 00:04:23 Chang gong as their Crown Jewel in low
00:04:23 --> 00:04:26 earth orbit the new crew is scheduled to
00:04:26 --> 00:04:28 return to Earth in late April or early
00:04:28 --> 00:04:30 May of next year continuing the steady
00:04:30 --> 00:04:32 rhythm of operations that has
00:04:32 --> 00:04:34 characterized China's presence in space
00:04:34 --> 00:04:36 their mission demonstrates China's
00:04:36 --> 00:04:37 growing capabilities in space
00:04:37 --> 00:04:39 exploration and their commitment to
00:04:39 --> 00:04:41 maintaining a continuous human presence
00:04:41 --> 00:04:43 in orbit let's move further out into
00:04:43 --> 00:04:46 space now a lot further fascinating new
00:04:46 --> 00:04:49 research has revealed that Miranda one
00:04:49 --> 00:04:52 of Uranus's smallest major moons might
00:04:52 --> 00:04:54 be hiding something remarkable beneath
00:04:54 --> 00:04:57 its bizarre surface a subsurface ocean
00:04:57 --> 00:04:59 what makes this discovery particularly
00:04:59 --> 00:05:01 surprising ing is Miranda's small size
00:05:01 --> 00:05:06 at just 471 km in diameter the moon's
00:05:06 --> 00:05:08 surface has long puzzled scientists with
00:05:08 --> 00:05:11 its unique Patchwork of jumbled terrain
00:05:11 --> 00:05:12 including what might be the tallest
00:05:12 --> 00:05:15 cliff in our entire solar system a
00:05:15 --> 00:05:18 massive 20 km drop called Verona rupes
00:05:18 --> 00:05:20 but it's What Lies Beneath this chaotic
00:05:20 --> 00:05:22 surface that's now catching researchers
00:05:22 --> 00:05:24 attention using Advanced Computer
00:05:24 --> 00:05:27 modeling scientists worked backward from
00:05:27 --> 00:05:29 Miranda's current surface features to
00:05:29 --> 00:05:30 understand what could have created such
00:05:30 --> 00:05:33 a complex landscape their findings
00:05:33 --> 00:05:35 suggest that beneath the moon's icy
00:05:35 --> 00:05:38 crust which is likely less than 30 km
00:05:38 --> 00:05:41 thick there could be an ocean up to 100
00:05:41 --> 00:05:44 km deep this hidden ocean probably
00:05:44 --> 00:05:47 existed in its fullest form between 100
00:05:47 --> 00:05:50 and 500 million years ago kept liquid by
00:05:50 --> 00:05:52 tidal heating from gravitational
00:05:52 --> 00:05:54 interactions with Uranus's other
00:05:54 --> 00:05:56 moons when these moons were in orbital
00:05:56 --> 00:05:58 resonance with each other their
00:05:58 --> 00:06:00 gravitational Tugs created enough heat
00:06:00 --> 00:06:02 to maintain liquid water beneath
00:06:02 --> 00:06:05 Miranda's surface what's particularly
00:06:05 --> 00:06:07 intriguing is that the ocean might still
00:06:07 --> 00:06:10 exist today albeit in a thinner form
00:06:10 --> 00:06:12 scientists believe if it had completely
00:06:12 --> 00:06:14 Frozen we would see evidence of
00:06:14 --> 00:06:16 expansion cracks on the surface features
00:06:16 --> 00:06:18 that are notably absent this discovery
00:06:18 --> 00:06:20 puts Miranda in the company of other
00:06:20 --> 00:06:23 potential ocean worlds like Saturn's and
00:06:23 --> 00:06:27 celus and Jupiter's Europa expanding our
00:06:27 --> 00:06:28 understanding of where liquid water
00:06:28 --> 00:06:31 might exist in our solar system it's a
00:06:31 --> 00:06:33 reminder that even in the coldest most
00:06:33 --> 00:06:35 distant corners of space the conditions
00:06:35 --> 00:06:37 for potential habitability might be more
00:06:37 --> 00:06:40 common than we once thought the findings
00:06:40 --> 00:06:42 are even more remarkable considering
00:06:42 --> 00:06:44 they're based on decades old data from
00:06:44 --> 00:06:48 Voyager 2's brief 1986 flyby it shows
00:06:48 --> 00:06:49 how modern analytical techniques can
00:06:49 --> 00:06:51 reveal new secrets from limited
00:06:51 --> 00:06:53 historical observations while also
00:06:53 --> 00:06:55 highlighting the need for New Missions
00:06:55 --> 00:06:58 to these Distant Worlds now let's double
00:06:58 --> 00:07:00 back to Mars where new finding suggests
00:07:00 --> 00:07:01 there may have been life there a lot
00:07:01 --> 00:07:03 more recently than thought new research
00:07:03 --> 00:07:05 from Harvard's paleomagnetics lab has
00:07:05 --> 00:07:07 dramatically shifted our understanding
00:07:07 --> 00:07:10 of Mars's potentially habitable past
00:07:10 --> 00:07:12 scientists have discovered that the red
00:07:12 --> 00:07:14 planet's protective magnetic field may
00:07:14 --> 00:07:16 have persisted hundreds of millions of
00:07:16 --> 00:07:18 years longer than previously thought
00:07:18 --> 00:07:21 lasting until about 3.9 billion years
00:07:21 --> 00:07:24 ago rather than disappearing around 4.1
00:07:24 --> 00:07:26 billion years ago this protective
00:07:26 --> 00:07:28 magnetic field generated by convection
00:07:28 --> 00:07:30 in the planet's iron IR core much like
00:07:30 --> 00:07:32 Earth's field today would have played a
00:07:32 --> 00:07:34 crucial role in defending the Martian
00:07:34 --> 00:07:37 surface from harmful cosmic rays the
00:07:37 --> 00:07:39 longer this Shield remained active the
00:07:39 --> 00:07:41 more time there would have been for
00:07:41 --> 00:07:44 potential life to develop and Thrive the
00:07:44 --> 00:07:45 research team reached this conclusion
00:07:45 --> 00:07:47 through Innovative analysis of Mars's
00:07:48 --> 00:07:50 impact basins these massive craters have
00:07:50 --> 00:07:52 traditionally been thought to show weak
00:07:52 --> 00:07:55 magnetic signatures because they formed
00:07:55 --> 00:07:57 after Mars's magnetic field had already
00:07:57 --> 00:08:00 disappeared however the Harvard team
00:08:00 --> 00:08:02 proposes a different explanation these
00:08:02 --> 00:08:04 weak signatures could instead be
00:08:04 --> 00:08:06 evidence that the craters formed during
00:08:06 --> 00:08:09 magnetic pole reversals similar to the
00:08:09 --> 00:08:11 way Earth's magnetic poles occasionally
00:08:11 --> 00:08:14 flip by studying the famous Allen Hills
00:08:14 --> 00:08:16 meteorite using a Quantum Diamond
00:08:16 --> 00:08:18 microscope the researchers found
00:08:18 --> 00:08:20 evidence supporting their theory of a
00:08:20 --> 00:08:23 longer lasting magnetic field this new
00:08:23 --> 00:08:25 timeline suggests Mars remained
00:08:25 --> 00:08:27 protected from harmful radiation during
00:08:27 --> 00:08:29 a crucial period when we believe the
00:08:29 --> 00:08:31 Planet still had liquid water on its
00:08:31 --> 00:08:34 surface the implications are profound if
00:08:34 --> 00:08:36 Mars maintained its protective magnetic
00:08:36 --> 00:08:37 field for hundreds of millions of years
00:08:37 --> 00:08:39 longer than we thought it means the
00:08:39 --> 00:08:42 window for potential life to emerge and
00:08:42 --> 00:08:45 evolve was significantly larger the
00:08:45 --> 00:08:46 planet would have remained warmer and
00:08:46 --> 00:08:48 wetter for longer with its atmosphere
00:08:48 --> 00:08:50 better protected from being Stripped
00:08:50 --> 00:08:51 Away by solar
00:08:51 --> 00:08:54 radiation This research challenges our
00:08:54 --> 00:08:56 previous assumptions about Mars's early
00:08:56 --> 00:08:58 history and opens up new possibilities
00:08:58 --> 00:09:00 about how long long the red planet might
00:09:00 --> 00:09:03 have been capable of supporting life
00:09:03 --> 00:09:05 it's another piece in the complex puzzle
00:09:05 --> 00:09:07 of Mars's transformation from a
00:09:07 --> 00:09:09 potentially habitable world to the cold
00:09:09 --> 00:09:12 dry planet we see today now speaking of
00:09:12 --> 00:09:14 Life on Mars how about this for an
00:09:14 --> 00:09:17 intriguing idea in the future here's how
00:09:17 --> 00:09:19 we could one day see trees growing on
00:09:19 --> 00:09:21 the Red Sands of Mars at least according
00:09:21 --> 00:09:23 to fascinating new research that Maps
00:09:23 --> 00:09:24 out the conditions needed to make it
00:09:24 --> 00:09:26 possible and the findings might surprise
00:09:26 --> 00:09:29 you scientists at the Warsaw University
00:09:29 --> 00:09:31 of Technology have been crunching the
00:09:31 --> 00:09:34 numbers on exactly how much we'd need to
00:09:34 --> 00:09:37 alter Mars's atmosphere to support tree
00:09:37 --> 00:09:39 growth they looked at everything from
00:09:39 --> 00:09:41 temperature requirements to atmospheric
00:09:41 --> 00:09:43 pressure and the length of growing
00:09:43 --> 00:09:45 Seasons needed interestingly the first
00:09:45 --> 00:09:47 Martian forests likely wouldn't take
00:09:47 --> 00:09:50 root where you might expect while on
00:09:50 --> 00:09:52 Earth trees grow best in tropical
00:09:52 --> 00:09:54 regions Mars's unique orbital
00:09:54 --> 00:09:56 characteristics mean the planet's
00:09:56 --> 00:09:58 southern hemisphere experiences longer
00:09:58 --> 00:10:00 warmer
00:10:00 --> 00:10:03 Summers this combined with the extremely
00:10:03 --> 00:10:05 low elevation of the helis Basin makes
00:10:05 --> 00:10:07 it the most promising location for the
00:10:07 --> 00:10:10 first Martian trees for trees to survive
00:10:10 --> 00:10:12 Mars would need significantly higher
00:10:12 --> 00:10:15 temperatures with much less dramatic day
00:10:15 --> 00:10:18 toight swings than it experiences now
00:10:18 --> 00:10:20 the growing season would need to last at
00:10:20 --> 00:10:23 least 110 Martian days the researchers
00:10:23 --> 00:10:25 mapped out precisely how much carbon
00:10:25 --> 00:10:26 dioxide would be needed in the
00:10:26 --> 00:10:28 atmosphere to create these conditions
00:10:28 --> 00:10:30 through the greenhouse of effect the
00:10:30 --> 00:10:32 whole concept might sound like science
00:10:32 --> 00:10:34 fiction but this research provides
00:10:34 --> 00:10:36 concrete numbers and specific locations
00:10:36 --> 00:10:37 that could guide future terraforming
00:10:38 --> 00:10:39 efforts while we're still a long way
00:10:39 --> 00:10:42 from planting the first Martian Forest
00:10:42 --> 00:10:43 understanding exactly what it would take
00:10:43 --> 00:10:46 brings us one step closer to potentially
00:10:46 --> 00:10:48 transforming the red planet into a
00:10:48 --> 00:10:50 second home for Earth life of course
00:10:50 --> 00:10:52 there are still major hurdles to
00:10:52 --> 00:10:53 overcome including establishing
00:10:54 --> 00:10:55 sufficient oxygen levels and protecting
00:10:55 --> 00:10:58 any plants from harmful radiation but
00:10:58 --> 00:10:59 having a clearer picture of the
00:10:59 --> 00:11:02 temperature and Atmospheric requirements
00:11:02 --> 00:11:04 gives future Mars colonists a better
00:11:04 --> 00:11:06 road map for what might be
00:11:06 --> 00:11:08 possible well it seems our hopes for a
00:11:09 --> 00:11:11 spectacular Halloween Sky show have been
00:11:11 --> 00:11:15 dashed Comet c224 S1 Atlas which
00:11:15 --> 00:11:17 initially showed such promising
00:11:17 --> 00:11:19 brightness after its Discovery in late
00:11:19 --> 00:11:21 September has met a fiery end in the
00:11:21 --> 00:11:24 sun's scorching embrace the comet gave
00:11:24 --> 00:11:25 us early warning signs that it might not
00:11:25 --> 00:11:28 survive its close solar encounter after
00:11:28 --> 00:11:30 an initial bright Outburst when it was
00:11:30 --> 00:11:32 first spotted it began to fade
00:11:32 --> 00:11:35 considerably in early October still
00:11:35 --> 00:11:37 astronomers held out hope that it might
00:11:37 --> 00:11:38 join the rare ranks of su grazers that
00:11:38 --> 00:11:41 survive their close solar passages
00:11:41 --> 00:11:43 unfortunately when the comet entered the
00:11:43 --> 00:11:45 field of view of NASA's Soho solar
00:11:45 --> 00:11:47 Observatory yesterday morning it was
00:11:47 --> 00:11:49 already showing signs of breaking apart
00:11:49 --> 00:11:52 as it approached within just
00:11:52 --> 00:11:55 33 miles of the sun's surface about
00:11:55 --> 00:11:57 1 and a half times the distance between
00:11:57 --> 00:12:00 Earth and the moon the Comet completely
00:12:00 --> 00:12:01 disintegrated what makes this
00:12:01 --> 00:12:03 particularly interesting is that
00:12:03 --> 00:12:05 calculations suggest this Comet had an
00:12:05 --> 00:12:07 orbital period of about
00:12:07 --> 00:12:10 953 years this means it may have visited
00:12:10 --> 00:12:12 the inner solar system before nearly a
00:12:12 --> 00:12:14 millennium ago only to meet its end on
00:12:14 --> 00:12:16 this final
00:12:16 --> 00:12:19 Journey while S1 Atlas joins the
00:12:19 --> 00:12:21 thousands of comets that have perished
00:12:21 --> 00:12:23 in similar solar encounters it's worth
00:12:23 --> 00:12:26 noting that some Su grazers do survive
00:12:26 --> 00:12:28 the most famous example is perhaps Comet
00:12:28 --> 00:12:31 Lovejoy which in 2011 survived passing
00:12:31 --> 00:12:34 just 87 mi from the sun's surface
00:12:34 --> 00:12:36 and went on to provide spectacular views
00:12:36 --> 00:12:38 for observers on Earth these close
00:12:38 --> 00:12:40 encounters with the sun give us valuable
00:12:40 --> 00:12:42 insights into both the composition of
00:12:42 --> 00:12:44 comets and the extreme conditions near
00:12:45 --> 00:12:47 our star while we may have missed out on
00:12:47 --> 00:12:50 a bright Halloween Comet this year the
00:12:50 --> 00:12:52 next great Comet could appear at any
00:12:52 --> 00:12:54 time that's the unpredictable nature of
00:12:54 --> 00:12:57 these Cosmic visitors that makes them so
00:12:57 --> 00:13:00 fascinating to observe
00:13:00 --> 00:13:03 and that wraps up our coverage for today
